Title: Stage drive method and stage unit, exposure apparatus, and device manufacturing method
Inventor: SHIBAZAKI YUICHI
IPC: G03F7/20
Filed: 2010-01-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a stage drive method and a stage unit suppressed in leak of liquid, to provide an exposure apparatus, and to provide a device manufacturing method.  <P>SOLUTION: When a stage state is changed from a first state where one stage (WST1 (or WST2)) is positioned at a first region directly under a projection optical system (PL), to which liquid (Lq) is supplied, to a second state where the other stage (WST2 (or WST1)) is positioned at the first region, both stages are simultaneously driven in the X-axis direction while being maintained close to each other relative to the X-axis direction. As a consequence, the first state can be changed to the second state with the liquid supplied between the projection optical system and a specific stage directly under the system. This enables to reduce the time from the completion of exposure operation at the one stage side to the start of exposure operation at the other stage side, enabling processing at high throughput. Further, since the liquid is always present on the image surface side of the optical projection system, occurrence of a water mark on an optical member, on the image surface side, of the projection optical system is prevented.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide an electronic apparatus with a structure capable of suppressing deterioration in gain of antenna characteristics, even if it uses an antenna device and a solar panel together.  <P>SOLUTION: An antenna device 6 includes a plate dielectric 6c, a radiation conductor 6a, and a grounding conductor 6b. A hole 6d is formed at the center of the dielectric 6c. Electrode pads 22 and 23 of a solar panel 20 at the side of the front surface of the antenna device 6 are connected electrically to a circuit board 11 at the side of the rear surface of the antenna device 6 through electric connection members 25 and 26 arranged in the hole 6d. Moreover, the outer dimension L1 of the solar panel 20 is smaller than the outer dimension L2 of the radiation conductor 6a. Thereby, in construction, the outer edge 20a of the solar panel 20 is not protruded from the outer edge 6a1 of the radiation conductor 6a. Therefore, the antenna device 6 is hard to be affected with adverse influence from the electrode pad 22 and 23 of the solar panel 20. Accordingly, deterioration in the gain characteristics of the antenna can be suppressed certainly and easily.  <P>COPYRIGHT: (C)2011,JPO&INPIT

Title: Semiconductor memory and operating method therefor

IPC: G11C11/15
Filed: 2010-02-02
Abstract: <P>PROBLEM TO BE SOLVED: To prevent malfunction of a semiconductor memory and to improve read margin.  <P>SOLUTION: A memory cell includes a variable resistance element which stores data according to a resistance value that has a hysteresis characteristic with respect to an applied voltage. A negative resistor circuit is connected in parallel to the variable resistance element via a read node. In read operation, a voltage setting circuit tentatively sets, to the read node, an initial voltage corresponding to a read current smaller than a threshold current value for rewriting data. The read circuit decides data logic stored in the memory cell, based on the read voltage of the read node which varies with a current, flowing in the variable resistance element and the negative resistor circuit, according to the initial voltage. By setting the initial voltage so that the read voltage varies in the direction opposite to the loop variation of the hysteresis characteristic, data can be prevented from being rewritten by an inverted resistance value.  <P>COPYRIGHT: (C)2011,JPO&INPIT
